The higher scoring players using it at the Milan ITC tend to win 1 game, sometimes 2 (out of 4 ) (based on the records I've kept). In 2018 Fabio Terpin scored 73 points off his 4 games, I don't know the separate results.
The army has so many options it may take a lot of experimentation to find the design that works for you.
One of the players in the UK has done very well with the inert version, with 4 Art(F) shooting over Bw. It's not unbeatable, though. Greg Russel used the inert version at CANCON a couple of years ago, I don't know if he won any games but he probably did.
You can extend your options by using mostly the same figures for Patrician Roman.
